This is very handy and light. Most importantly, it is a heavy gauge, so is not subject to failure. It fits perfectly in my waist pack and I needed it on the trail just the other day. With this tool in hand, I quickly loosened the rear axle bolt and was able to run up a notch on the chain. What a life saver. The downside is the handle is short, so be prepared to use a lot of leverage. Great tool for the trail.
